Linux under compilation installation Log4cxx

A Project Server side under the Linux platform, the open source log library Log4cxx, this library is a sub-library of Apache project. The function is very good. The following is a record of its compilation and installation process.

Log4cxx's official is http://logging.apache.org/log4cxx/index.html, I use 0.10.0 version.

In order to compile it, also need two auxiliary library, Apr, and apr-util, can download http://apr.apache.org/download.cgi here, I use the version is apr-1.3.8.tar.gz and apr-util-1.3.9.tar.gz.

The first step installs apr-1.3.8, the order cannot be wrong, it must install first

$tar ZXVF apr-1.3.8.tar.gz

$CD apr-1.3.8

$./configure--prefix=/usr/local

$make

$SU Root

$make Install

Then install apr-util-1.3.9

$tar ZXVF apr-util-1.3.9.tar.gz

$CD apr-util-1.3.9

$./configure--prefix=/usr/local--WITH-APR=/USR/LOCAL/APR

$make

$SU Root

$make Install

Configure option--WITH-APR=/USR/LOCAL/APR Specify the location of the APR library

Finally, we can install Log4cxx.

$tar ZXVF apache-log4cxx-0.10.0.tar.gz

$CD apache-log4cxx-0.10.0

$configure--prefix==/usr/local

$make

$SU Root

$make Install

Because compiled into a shared library, and finally set the next search directory, edit ~/.BASHRC, add the following two lines

Ld_library_path=/usr/local/lib

Export Ld_library_path

OK, so log4cxx is ready to install.

Finally write a program, test under.

#include <log4cxx/logger.h>
#include <log4cxx/logstring.h>
#include <log4cxx/propertyconfigurator.h>

int main (int argc, char* argv[])
{
using namespace Log4cxx;

Reading configuration Files
Propertyconfigurator::configure ("Log4cxx.cfg");

Establishment of two logger
Loggerptr logger1 = Logger::getlogger ("Traceyourmama");
Loggerptr logger2 = Logger::getlogger ("Patch");

Log4cxx_trace (Logger1, "tracking");
Log4cxx_warn (Logger1, "warning");
Log4cxx_debug (Logger1, "commissioning");
Log4cxx_assert (Logger1, False, "assertion");
Log4cxx_fatal (Logger1, "deadly");

Log4cxx_trace (Logger2, "tracking");
Log4cxx_error (Logger2, "error");
return 0;
}

Compiling links

$g + +-o main main.cpp-llog4cxx

OK, finish the manual.

Finally install Log4cxx when there will be errors, missing header files, according to the wrong file to add
